Easy enuff,Will a 3.8 buick engine out of a 93 fwd work in our f bodys? I can get one for 300. I see where the 89 firebird had a few cars mad with buick 3.8 turbos

 

This has been answered many times...no, it will not fit without modifications, a search, or reading some of the stickies up top would have told you all you need to know.

 

It'll fit, but it's not an easy bolt-in. You'll need to fab up some motor-mounts because the 3800 and 3.8 are different in a few regards. However, I've heard that even the FWD engines have bosses to mount in a longitudinal orientation.

Custom motor-mounts, and that's about all that's custom.

 

I checked over the stickys,they didn't help out.Besides not everything is in them.Fallen2603's answer was much more helpful!

 

Along with dealing with starter placement, belt drive, intake direction (not sure how easy it is to turn the 3800 intake around), and a few other things.

 

Starter placement is same place on RWD and FWD 3800's.

Accessory-drive...don't know, but would probably fit.

Intake-manifold...since I think you have an L27, which has a one-piece intake-manifold, you'll probably have to get one of the two-peice manifolds off a RWD 3800.

Best place to start would be a 3800 out of a '95+ 4th-Gen Camaro/Firebird with transmission and harness.

 

How hard is a RWD 3.8 buick to put in.If they came factory then there has got to be a fairly simple way

 

3.8 buick is a 90 degree motor and our thirdgen v6's are 60 degree motors.....so youd need alot of fabrication, im thinking a new tranny, motor mounts, belt housing. It would be just as hard as a V8 swap so its not just a bolt on motor unlike any 2.8, 3.1, or 3.4 thirdgen 60* motor.

 

Here is part of a sticky on how to get the most out of your V6. You should read the hole thing.

*Last but not least are the 90* v6s, I honestly do not know much about them, but I will give the basic info I do have on them.
There are several variants, a RWD 3800 that was in the late model 4th gens, a 4.3 that has been used in trucks and is basically a castrated 5.7(2 cylinders lopped off) And some front wheel drive variants, and whatever the grand nationals had. Any one of these engines has more power potential than the 60* v6 engines because of their displacement advantage, I could see one hitting 700, if not 800+ horsepower(with boost) for the non 4.3 ones(In fact, I'm pretty sure its been done). They do however have a downside, because of their 90* angle, they are not naturally balanced, and I may be wrong about this, but I believe spinning rod bearings is somewhat common because of that, also because of this angle, you will not be able to use your stock transmission, they will require a bit of fabrication with motor mounts, and probably an ecm swap, some of the engines are turbocharged or supercharged from the factory, the 4.3 engines I believe don't have a lot of aftermarket, or the parts that you can get aftermarket are expensive, I am uncertain.

My basic opinion is, the engine has awesome power potential, but requires a lot of work to swap, it is also unbalanced due to its block angle, in my personal opinion, a v8 is a better option, simply because it is as much work swapping in one of these as a v8, that being said many people love them, if you want to be really unique, or stay v6 but have more power than a 60 degree v6 can offer, want a challenge or big project, than this engine is for you. I am honestly guessing here, but power output for these is probably going to be 400 or so N/A, 700+ with turbocharging, 550+ with supercharging. For swap info, you will have to do some digging I'm afraid, as I don't know of any readily available information on it.

 

Well I guess going to the history forum would be best to learn more about the 3.8 turbo charged buick engine that was put into a handful of 89 firebirds.I'm just wondering what they did.

 

(TTA) They were from factory like that. Just a dif engine code, IMO you could turbo a 60* motor for alot less$$ and get the results. Lots of info on here about that also.

 

So the 3.8 buick was no big deal?It's the turbo that dose it all?I've done the 3.4 swap in place of a 3.1.So thats only .4 differance anyhow!

 

Well the turbo Trans am is a great motor but if you already have the 3.4L in your car your be better off turboing that one. It would be alot easier and cost less. If your just looking for some Hp in a V6 and not specifically haveing a 3.8L SFI turbo then just play with the motor you have. Thats in my own opinon though.
